Touching any of the tome’s pages with bare skin is dangerous, for to do so requires the victim to make a Fortitude save (DC 20) or become infected with a spore sickness. Failure indicates death, and the resulting corpse begins to transform into a random ooze, jelly, or pudding monster. This transformation takes 4d4 rounds, and the new creature attacks the nearest being, having no memory of its former life. Creatures that successfully save must endure green hair, which can be returned to normal via a successful application of a remove curse spell cast by a 20th-level spellcaster.
